Friction clutches for use in drive strand of motor vehicle, have press plate rotatably fixed against housing, and lever springs axially supported at housing using lever arms that rotate with lever elements in circumferential direction

摘要

The clutches (2, 3) have a press plate (5) rotatably fixed against a clutch housing (9) and movable in an axial manner. The press plate is opened in a force free condition under pre-stressing of energy storage units i.e. laminated spring units (10, 11), that are axially supported at the housing. Lever springs (7) are made of sheet metal and axially supported at the clutch housing using lever arms (18). The lever arms are laid out from the lever springs. The lever arms rotate with lever elements (17) in a circumferential direction, where the elements are connected with one another.
